TO BETHLEHEIVI COKE-QUENCHING CAR,

Application led February 10, 1927, Serial No. 'f6-7,125.

` This invention relates to railroad cars adaptedy to contain materialheated to substantial temperatures and quenched, as for example cokequenching cars.

Cars of this type having a sloping bottom and side discharge doors arewell known in the art,but an objectionable feature of such devices hashitherto been the wear and tear on the fioor plates due to their warpingand cracking under sudden changes of temperature, with the result thatafter being in service a short time portions of the` coke charges aredropped through the floor and lost.

A further difficulty has arisen, due to the outward bulging of the sideplates, and the 'consequent interference with the Jreevand easyoperation ofA the dischargingl doors.

It has also been recognized as desirable that the quenchingy water bepermitted' to drain from the car as quickly and completely as possible`and that the cooling eiiect of thel quenching water be supplemented byexposing the heated portions of the car structure to air currents,before the car be reloadedl with another' charge. vrIhese features havenot hither-tol been real-ized in quenching cars of'linown type.

This invention has therefore for an object, a design of floor plates,less susceptible to distortion and damage under rquenching conditionsthan those used hitherto.

A further object of this invention is to provide an improveddesign ottbracing members for the discharge side of the c ar, waereby the bulgingof the-side platesy may be substantially overcome.

Further objects of this invention are to provide improved drainagemeans, whereby the quenching water may be quickly and completely removedfrom the coke, and to provide means for the efficient air-cooling ofthose portions of the structure, that have been most exposed to the hightemperature Y of the incandescent coke.

p Refeiiringf'tofFigs.: 5, 6, 7 and v13,1 show floor plates .l1 havingtheir edges downturned so as to;i rest on the longitudinal supportmembers l2 and onthe widelange of inverted railsections? disposedtransverse- Suflflicient clearance is provided between .adjacent platesto permit their free expansion when heated; but r4'the open joints lso.formed are masked by the members @and the `rail flanges 13. De

`pendentribs 15 are provided oni the lower lmember-"s 12 andtheinverted? rail sections by suitable lliol'tsy i4 `the heads of thelatter' being recessed in the plates. l The bolt holes provide suHicientclearance tor the free cxpansion and contractionot' the plates. In Fig,9 I show a plain `view oi' typical plates 1i used in all parts of. thecar floor except those adjacent the discharge doors, which I show 'at l1in Figs; `5, 6 and l0.

also' showin Figs land 11, perforated .and ribbed sidepl'aite's 16'havinrg'lower projecting portions 17 disposed to the right and lett of'adjacent plates alternately. These plates are suitablyfsupported by, andattached to a longitudinalfiside meinber'lS of thelcar. Plates. to eachhand' when assembled in pairs have their perpendicular edges contiguousand their ribbed surfaces 19 exposed exteriorly of the car. Thedischarging doors comprise the right and left hand perforated plates 20shown in detail in Fig. 8, having ribs 21 on their exposed faces. Theseplates are suitably drilled for attachment to a member 22, whichconnects the separate plates, so that they may be operatedsimultaneously by any suitable device, as for example, by an aircylinder. The plates are further drilled for attachment of hinges 23,whereby the plates may be suitably suspended from a longitudinal member18 of the car structure.

As will be observed in Figs. 1 and 5, spaces are provided in theassembly of the side plates 16, the door plates 2O and the floor plates11 and 11 for the drain pockets 25. These pockets are defined by upper,lower and 'rear bracing plates shown respectively at 26, 27 and 28 inFigs. 2, 3 and 4. rlhe vupper edges of bracing plates 26 and 28 areflanged to right or to left hand, in such a. manner as to be susceptibleof assembly in pairs and form an upper closed joint 29. The faces of thebracing plates are further provided with air cooling strengthening ribs30 on the same sides as the right and left hand upper flanges abovementioned. Suitable flanges 31 and 32 are also provided on Vthe obverseside of the plates for securing the bracing plates 26, 27 and 28 to oneanother and a flange 33 for securing the upper bracing plates 26 to theside plates 16. The

y lower and therear bracing plates 27 and 28 have flanges 34 at theirlower edges for attachment to the supporting members of the carStructure. In Fig. 12 I show my preferred method of securing a right andleft hand bracing plate 27 to the flange 13 of an inverted rail sectionforming the cross member of the car, together with a portion of adjacentfloor plates 11 with their dependent ribs 15, said plates beingsupported at their longitudnal edges by the longitudinal support members12.

It will be evident from the above description, that the floor plates 11are so disposed in regard to their supporting means 12 and 13, that theclearances provided between the plates for their expansion are backed upand masked by said supporting means. The absence of overlapping jointsin my design also renders the removal, or insertion, of the individualplates an easy matter. 1 The deep ribs 15 on the under surface of theplates which project below their points of support, serve tosubstantially strengthen the plates and to dissipate the heat therefrom.Similarly in the case of the side plates 16 and the door plates 20 theexternally exposed ribs 19 and 21 serve the double purpose ofstrengthening and cooling the plates which are in contact with vthe hotcoke. YIt will also be evident that, the bracing plates 26, 27 and 28disposed in pairs transversely of the car and .secured to the sideplates 16 and the sloping floor ofthe car, serve to prevent the formerfrom bulging and therefore maintain the easy closing of the dischargedoor. The bracing plates moreover, when assembled in the manner showndefine a pocket closed upwardly but open downwardly, into whichquenching water may be quickly and effectively drained from the cokethroughfthe perforations in the bracing plates. As in the case of the;other parts of the cai in immediate contact with the hot coke, thebracing plates 26, 27' and 28 have strengthening and heat dissipatingribs 30 on theirlsiirfaces which are exposed to air cooling, that is tosay towards the pockets.

By these several. improvements, I have been able to substantiallyminimize the serious degradation of the exposed parts of a colicquenching car, and have therefore increased its length of service toamarked degree.

lVhile I have shown my invention` in but one form, it will be obvious tothose skilled in the art that it is not so limited, but is susceptibleof various other changes and modifications without departing from thespirit th-ereof, and I desire, therefoiey that only such limitationsshall be placed thereupon as are imposed by the prior art or as arespecically set forth in the appended*v claims.

Having thus described the invention what I claim as new and desire tosecure by Letters Patent is:

In a coke quenching car vhaving a floor inclined transversely fromits charging to its discharging side, the combination of iioor plateshaving their adjacent edges spaced for expansion, means to support theadjacent longitudinal edges of the plates, perforated side members atthe discharge side of the car, perforated discharging members dis-`posed beneath the side members, certain of the side members and certainof the discharging members being spaced for insertion transversely ofvertical members therebetween, said members defining pockets fordraining quenching water from the car.
